E. H. MccLEAsE l SIDE HOOK FISHING TOOL shown in Figs. l and 2 as a lostdrill collar C, tilted across a naked hole in such manner that it cannotbe speared or overshot by a tool.

There is mounted in the segn'ient 2 a slidin?,` segmental hool 5 fittedin ways in the body 2 and being` slotted at G to bear on antiiirictionrollers 7 on pins or screws 8. The front, effective end of the retractedhooi; may be iiush with the near lip 3 01' the bor y and its inner endis inclined helically 'to :match with a cam heel l of the lower end oiya legil slidably guided and retained in a boot or stein l2 extendingfrom the top end and one corner of the body 2 which is recessed at 13 toprovide ior the upward movement of cam l0. rlhe leg; 11 is slotted toreceive retaining screws 14 at suitable points.

The hook member may be provided with a contractile spring 15 drawing itbach against the face of the cam heel 10 which may be provided withantiiriction rollers 18, Fig. 4.

It will be seen that if the cam heel 10 is moved relative to the body 2,the hook 5 will be thrust outwardly from the lip 3 with a circularaction about the center of the body 2 andso will move across the openmouth between the opposite lips 3, as shown in Fig. This willveiectually encompass the located i'ish by the parts 2 and 5 of the vtoolso that ifthe tool be now elevated, the grappled iishv will be pulledfrom the hole.

To insure effective grappling of a fish. the body 2 may have interiorshoulder means 2a and toothed, slip jaws 2O which may be vieldinglysupported on springs 2l and bearing` voninclined back walls 22 tendingto thrust the jaws inwardly if, and as, they press down when brought upagainst the surface of a fish to be pulled out. v

The outer nose of the curved hook 5 is shown as provided with ashoulder` 5a in which is provided a. slip jaw 20'. The shoulder 5a mayrecede into a recess 23 therefor in the near lip 3. Y y

i/Vhe'n a fish having a collar or shoulder is taken it will rest on theshoulders 2x1-5a. If the fish has no shoulder, the slip jaws 2O willbite into its smooth surface.

Effective movement of the heel 10 to set the hook 5 may be accomplishedlin divers manners. As here snown the shank or boot 12 has a piston head25 coaxial withthe body 2 and having a packing 2G tightly fitting andkworking in a cylinder 28 which is att-ached to the upperend of the leg`ll lying in the boot l2.

The piston head'25 is attached to the lower end ot the' tubular stem 30having ports 3l opening` below` the cylinder head 29 and above pistonThe head 29 has a gland 27 on which seats one end of a spring 32, whilethe opposite yend bears against a contact flange 'fixed on stem`30,which is shown as attached by a reducer 34 and joint 35 to a drill pipe3G by which the tool device is carf ried and, when positioned at a fishin a hole,

The function of the spring is to thrust the cylinder and its associatedparte down as to piston head 25 and so push down leg ll and heel Ofandallow the hoolr 5 to stand retracted in its pocket in the body 2.v v

The toolis lowered into a hole, preferably full of liquid, until thebody 2 engages the lt is then maneuvered until it is felt to pass aboutthe sides of the iish. When this position is established, as certainlyas may be, then pressure ot liquid vas from a pump (not shown) in turnedinto the drill pipe 36 and its pressure above piston 25 forces thecylinder 28 upwardly'along piston head 25 and in so doing pulls up legll and heel l0 and this thrusts out the hook 5 which moves across themouth between lips 3-3 lVhen the cylinder has been pressed up to theproper degree for projecting` the hook 5, it'urther movement by pressureis stopped by opening of valves 38 in cylinder `head 29, when theirstems 39 abut the stationary flange 33 on the drill pipe part 30.Springs LlO'tend to hold the valves to their seats 4:1 in head 29. Whenthe valves are opened pressure of fluid in the cylinder isreleased andthe pump isst-opped orits discharge is diverted trom the drill pipeline. rlhe toolk is then pulled with its fish resting within the body 2and-hook 5.; f

' It the fish is missed the hydraulic pressure is released. The spring32 then forces the cylinder 28, the leg 1l and the cam heel it), totheir lower-most position. rlhe spring 32 is of sutiicient strength toforce the cylinder 28 down while pressure of head of liquid in the openwell and open drill pipeabout bal ance, and this will cause the cam heell0 to fall back from its raised, el'iective position and allow the hookto retract, after'which the pump is again thrown onto the drill-line forLrepeat action until the iish is caught.

When a ish is caught, its load on the hooli 5 will prevent its beingretracted.

When repeat action is not desired, I provide means to lock the valves 38open after the rst lift of the cylinder 28. This means is shown in Fig.9 as comprising` a simple snap latch 42 arranged so as to engage a partof or on a stem 39 when the valve 38 there of has been pushed oit itsseat in cylinder head 29.

So long as the valves are held open against the action ot the liquidpressure in the drill pipe, the liquid can drain freely out of the pipeand into the hole, as it is elevated and the stands broken out of theline.

A` slightly modified,y form of @the y cam l leg llisshown in Fig'sQlOand 11.
